津桥湖有压隧洞衬砌结构计算分析

摘要

隧洞的衬砌设计关系到其本身的安全性与实用性，尤其是有压隧洞在泄洪过程中，高水头、高流速对洞身的安全性构成严重威胁，科学合理的钢筋混凝土衬砌设计对隧洞安全及缩短施工期十分有利。本文通过介绍隧洞的受力情况，采用理正岩土系列软件对有压隧洞进行衬砌设计，并通过 PC-1500程序集中的G-12加以校核以满足稳定、运行安全的要求。%The relationship between the tunnel lining design to their own safety and practicality ,especially in the pressure tunnel spillway during high head ,high flow rate of the cave itself pose a serious threat to securi-ty,scientific and rational design of reinforced concrete lining tunnel safety and shorten the construction period of very favorable.This article describes the forces through the tunnel ,using the rationale being geotechnical software series for pressure tunnel lining design carried through PC-1500 program focused G-12 to be checked in order to meet the stability and operational safety requirements.
